|The other day at work we had a debate about being productive and a few people were surprised when someone said "if you work with computers it's nearly impossible to have your brain wired in productive tasks for more than, on average, 4 hours a day" :-)|
Definition of productive hours for this poll: time spent on researching, designing, debugging, testing, coding, supporting, refactoring or any other technical task directly related to these which makes you get in "the zone" or totally focused on a problem.
Exclude: time spent on meetings (no matter the subject, as they can be productive for the team but not for you), managing people (only indirectly related to technical stuff), lunch time, coffee breaks and browsing the web (decompressing) and other minutes not spent on solving problems with computers.
Consider: a somewhat long time span, not just the current week or month.
...and have a happy monday :-)
